QUESTION 6 An аmbulаnce with its siren оn mоves аt a cоnstant speed of 37.5m.s-1 to an accident scene. A police officer sitting in his stationary vehicle at the accident holds a detector in his hand. The detector can measure a maximum frequency of 580 Hz. Ignore the effects of wind. 6.1 Calculate the frequency of the sound waves produced by the sound source when the detector registers a maximum reading. Take the speed of sound in air as 340m.s-1. (4) 6.2 The phenomenon observed here is called the Doppler effect. Define the Doppler effect. (2) 6.3 The speed of the ambulance increases to 41.5m.s-1. Will the detector now be able to register a reading? Give a reason for your answer. (3) 6.4 How does the frequency that the ambulance driver hears compare to the frequency that the ambulance's siren produces? Write MORE THAN, LESS THAN or THE SAME. Give a reason for your answer. (2) 6.5 How is the Doppler effect perceived with sound waves? (1) 6.6 How is the Doppler effect observed with light waves? (1) 6.7 Explain ONE positive impact of the Doppler effect in the medical field. (2) A car moving at a constant speed of 140km.h-1 behind a truck traveling at a constant speed of 110km.h-1 in the same direction sees a red sticker on the back of the truck which says: If this sticker is blue, you are driving too fast. 6.8 Use the Doppler effect to explain the statement on the sticker. (2) 6.9 Refer to the speed of light to explain if the statement on the sticker is possible. (2) [19]
